Working with stainless steel surfaces

Resistance
Information on the resistance of stainless steel:
● The stainless steel surface is not fully resistant against the chemicals listed below:
– Hydrochloric acid
– Sulphuric acid
– Sodium hydroxide
– Chlorine
– Chlorides
Do not clean the stainless steel surface with these chemicals or with similar acids or
caustic solutions.
● Acid steam develops, for example, when tiles are cleaned with hydrochloric acid, and is
also harmful to the stainless steel. If the stainless steel parts are unintentionally
contaminated with hydrochloric acid, rinse these off immediately with plenty of water.
● Clean the stainless steel surface with a cleansing agent without active chlorine.
